1) Don't do Local Apps (The thought experiment is often wrong) eg I'll show
   you a site that will consistantly crash a workstation with 128M ram!!
   (mozilla on server, using workstation DISPLAY)

2) When everything works and then you decide to do 'local apps' consider
   what and why.
   Run in another 2 machine environment. Then transfer to ltsp environment.

My opinion: unless you have 500M on the workstation you ought not to be 
running apps locally. I think apps should be run on the server. 'local apps'
should be things like 'seti at home' that use the spare computing power, but
not system resources where system is defined as 'ltsp server, network and
workstations'.

The questions you are asking suggest that you are doing 'thought experiments'
(wouldn't it be nice if)
Since you are using ssh to the workstation I guess you are using ltsp-4. 
Did you build Firebird in the ltsp environment?
You should not try copying arbitary libraries from an arbitary server to the
ltsp environment. See all the build motivation for ltsp-4.
