Sorry, but 'SSL VPN' is generally understood to be a VPN where the client
is the web browser. For example, http://www.whalecommunications.com/
(has a nice whitepaper somewhere on SSL VPN's and specifically their
'e-Gap' thingy which I mean to duplicate some day ;-)).  The trade-off
is the same as always: no client install, but less functionality.

OpenVPN is more a 'traditional' VPN in that it requires software at
both ends but in turn lets you route arbitrary traffic. It is much more
like IPsec, but has (in my eyes) the advantage that it doesn't need a
separate IP protocol and is easier to install and configure (no kernel
drivers and stuff like that).
