This whole 'no out the same interface' game is why I really dislike
a PIX for VPN termination. Even a cheap router is a good call. (1801).
Its much cheaper than an ASA, can hang off another interface, etc.

don't think you can generically turn around and send data UNENCRYPTED
out of the same interface it came in -- only encrypted.
