Are they any problems running the wine emulator on SL5x?  I recall wine
used to be part of RedHat's distributions.  But, I dont see it in SL5x. Is
or was there a reason why it was left out? It appears to be part of the
EPEL repo which I am not familiar with.

One of my users wants it on a server.  I'm reluctant to install it if it
will hang up the server.  I've never used it myself.  I've played around
with VMWare and while it works, there were the occasional hiccups. Which
is ok if it's your own machine.  Not so good on a multi-user server.

I'd appreciate any advice.  Thanks!
