Define "rarely". As long as you can ssh in a server, you can use this.
This is very handy for e.g. laptop users, to use internal resources
from the outside (smtp, pop3, intranet www server, ...)

ssh is userland-only and so can run on any platform with a C compiler and
sokets (you even have ssh servers for NT :). IPsec needs kernel support,
which requires more than "download sources and compile".
