Does anyone have experience of alternatives to Citrix (maybe Linux ones???). We have a 20 user network over 2 sites linked via a 2.3M SDSL link, we're serving desktops not apps, basically Office plus accounting and sales/order processing. We also run NFuse for remote access as a couple of our guys need access when travelling.

Citrix has worked really well for us but we can't really afford the £10k or so it'll cost to put in a new server and upgrade from NT4 TSE & MF1.8 so any advice/opinions appreciated.

Not my baliwick, but..
