from what you describe, you avoid the problem on the web server by moving it to
another physical server/device... but the problem itself (requires 1 unique
IP/port conbination per SSL host) still exists.

Bottom line, if you only have 1 IP address you can only use 1 SSL cert UNLESS
you start assigning other port combinations per SSL cert...  messy at best.
