Got it to work!!!
Went out today and got a 4g card, put it on Win 7 mac mini and turned on ICS. Added a few ports for Blackberry Enterprise server, put the whole thing in front of my Checkpoint router and shebang, it's running like a charm. Internet on desktop pc's, exchange email (via pop3 connector) and BES to blackberries.
Now I can take a breath and wait for verizon to restring all that damaged fiber out on the street!
