Well then since I have an abundance of 2 meter FM equipment and I can only use
one 2 Meter HT at a time I think between job interviews and other things I have
to get done around the house I will dig out one of my older FM rigs, maybe my
OLD Drake TR-22C and set up New York City's first VHF pskmail server.  Of course
who am I kidding.......with the way life tends to go it may take more than this

I also have several older laptops around....mostly with older versions of
FreeBSD installed.  I wonder if anyone has any real world experience on what the
minimal pskmail server needs?  I note that fldigi needs X11, which is
unfortunate as in server service running an X application is pretty much a waste
of CPU cycles.

I was looking at trying to set up a server on something in the Pentium II 100Mhz
range, just because I have several laptops of that era just gathering dust. 
They all have sound and the sound works fine for playing/recording ogg audio
