We're concerned because most crisis call lines are not the phone bank you see on TV, but volunteers that work at home. As a crisis line volunteer, you want your home number blocked so that the client calls the crisis line and not you.

Some of the people we deal with aren't particularly stable and may try to latch on to the crisis worker - these, if they go into common use, could cause mental health issues for the users of crisis hotlines, AND the volunteers.

I've seen an (illegal) hack to turn Windows XP into a terminal server. I'm not sure how legal this is (since there's no reference to purchasing additional Windows licenses), but ThinSoft's WinConnect has a commercial program that does the same thing the hack does. There are problems with WinConnect: the license is really harsh (PC died? Tough crap, buy another license), and Windows XP doesn't regulate resources well in this mode: if six people launch the same app, you have six separate instances (rather than one split) run, with all the resource requirements six times over.
