App-specific proxy settings?

[dbfriends]

Hi all,

I've been playing with SSH tunnelling and proxying over the last couple of days and have things up and running how I'd like. The next step is to get specific applications to use proxy settings - while the others simply ignore them. I can obviously do this for Firefox, which has its own proxy dialog, but I wondered if there was anything I could install which would allow me to use my proxy settings for only a couple of apps?

Thanks in advance!
