[p2p-hackers] Number of pinholes supported by low-end NATs?

Does anyone have any idea how many pinholes a P2P application
can have open at one time through a typical low-end NAT box?

Could a P2P application maintain connections to 30 peers simultaneously?
What about 50 peers? Or 100 peers?

Do the numbers differ if the messages are carried over UDP vs TCP?

(Note: My interest is in limitations in the NAT box, and NOT in any  
limitations in
the Windows, Mac, Linux, ... box on which the P2P application is  

Just wondering if anyone has any solid data in this area.
