Just to check - which ones can FTS talk to at present? Certainly gridftp, I believe http, not sure about xroot? And do we know whether globus online can manage Webdav<->webdav transfers?

I'm really not sure why this continues to be vexed; if you're building a closed system just for yourself then closed tools can work fine - once you've make sure that all of your bits talk to all of your other bits, you're good. If you're trying to work with more than two other people with their own stuff going on, their own priorities, and their own funding, then you're getting nowhere without an open standard (de facto is fine) with at least one (more or less) open source implementation. That leaves a lot of niches where closed tools can work, but this isn't one of them.
