Doze apps in a browser? OS solution?

[sam_uk]

Hi I work for an organisation that has done a few LTSP intstalls and Linux migrations for clients.

We often run into situations where a client needs one or two legacy applications supported.

I came across this proprietary service that will run your windows application over a network in a browser;

http://www.graphon.com/

It seems like a good solution for those cases. We would obviously prefer a FOSS solution.

Does anything like virtualbox support turning applications into net service in the way that Graphon do?

Thanks
