Hi Samo,
actually you can do it now. The current release of PushToTest comes with soapUI installed and this is the way we see it being in the future as well.
go to PushToTest and try it! There is also a lot of good aditional info for the Web Service Test Community.
www.pushtotest.com As you suspect it's an integration where we share the artifacts (soapUI Project files)
