Thanks, that's a very helpful conclusion and actually a perfectly workable
solution for now. I will keep a close eye on the blog for future
developments in this area, and I certainly hope that I will be able to make

Let me just tie this up by thanking you all for your extensive and very
helpful replies. It's been a very enlightening discussion.

Much obliged,

Gertjan
