The belt press of claim 1, wherein the belt press is arranged on an ATMOS system. 3. The belt press of claim 1, wherein said permeable belt is capable of running at a tension of between approximately 30 kN/m and approximately 60 KN/m. 4. The belt press of claim 1, wherein said permeable belt is resistant to at least one of hydrolysis and temperatures which exceed 100 degrees C. 5. The belt press of claim 1, wherein the support surface is static. 6. The belt press of claim 1, wherein the support surface is arranged on a roll. 7. The belt press of claim 6, wherein the roll is a vacuum roll having a diameter of between approximately 1000 mm and approximately 2500 mm. 8. The belt press of claim 7, wherein the vacuum roll has a diameter of between approximately 1400 mm and approximately 1700 mm. 9. The belt press of claim 1, wherein the belt press forms an extended nip with the support surface. 10. The belt press of claim 9, wherein the extended nip has an angle of wrap of between approximately 30 degrees and approximately 180 degrees. 11. The belt press of claim 10, wherein the angle of wrap is at least one of: between approximately 50 degrees and approximately 140 degrees; and between approximately 50 degrees and approximately 130 degrees. 12. The belt press of claim 9, wherein the extended nip has a nip length of between approximately 800 mm and approximately 2500 mm. 13. The belt press of claim 12, wherein the nip length is between approximately 1200 mm and approximately 1500 mm. 14. The belt press of claim 1, wherein the permeability value is between approximately 300 cfm and approximately 800 cfm. 15. The belt press of claim 1, wherein said permeable belt is an endless belt that is at least one of pre-seamed and has its ends joined on a machine which utilizes the belt press. 16. The belt press of claim 1, wherein the paper web facing side of said permeable belt comprises a warp count of between approximately 5 yarns/cm and approximately 60 yarns/cm. 17. The belt press of claim 16, wherein the warp count is between approximately 8 yarns/cm and approximately 20 yarns/cm. 18. The belt press of claim 1, wherein the paper web facing side of said permeable belt comprises a weft count of between approximately 5 yarns/cm and approximately 60 yarns/cm. 19. The belt press of claim 18, wherein the weft count is between approximately 5 yarns/cm and approximately 20 yarns/cm. 20. The belt press of claim 1, further comprising: a first fabric and a second fabric traveling between said permeable belt and said support surface; said first fabric having a first side and a second side; said first side of said first fabric being in at least partial contact with said exterior surface of said support surface; said second side of said first fabric being in at least partial contact with a first side of a fibrous web; said second fabric having a first side and a second side; said first side of said second fabric being in at least partial contact with said first side of said permeable belt; and said second side of said second fabric being in at least partial contact with a second side of said fibrous web. 21. The belt press of claim 20, wherein said first fabric comprises one of a permeable dewatering belt, a felt, a woven fabric, and a wire. 22. The belt press of claim 20, wherein said second fabric comprises one of a structured fabric and a TAD fabric. 23. The belt press of claim 21, wherein said fibrous web comprises a tissue web or hygiene web. 24. A fibrous material drying arrangement comprising: an endlessly circulating permeable extended nip press (ENP) belt arranged on a belt press and being guided over a roll; said ENP belt having a tension of between approximately 20 kN/m and approximately 100 KN/m, a permeability value of between approximately 100 cfm and approximately 1200 cfm, a surface contact area of the paper web side that being between approximately 0.5% and approximately 90% when not under tension, and an open area of between approximately 1.0% and approximately 85%. 25. A method of subjecting a fibrous web to pressing in a paper machine using a permeable extended nip press (ENP) belt arranged on a belt press and which is capable of being subjected to a tension of between approximately 20 kN/m and approximately 100 KN/m, wherein the ENP belt comprises a permeability value of between approximately 100 cfm and approximately 1200 cfm, a surface contact area of a paper web side that is between approximately 0.5% and approximately 90% when not under tension, and an open area of between approximately 1.0% and approximately 85%, the method comprising: applying pressure against a contact area of the fibrous web utilizing the ENP belt of the belt press.
