Sounds like Neil Finlayson is having some exciting ideas ("Groove becomes Hypercard through InfoPath spawning"). Well, I suppose that beats the InfoPath-looks-like-Notes comparisons on the newsgroup :-)

I'm impressed with InfoPath's flexibility. But to use HyperCard terminology, it's like a single (XML/XSLT/XSD) card, not a stack. A distributed stack-of-cards with HyperCard-like ease of design, though, would be lots of use.

Sometime, we'll get there...
