I took part in this program http://www.inventorium.org/events/swequity-wales-spring-2013... that runs in Dublin and now North Wales. Great idea - check out the info packs to see how it works. No reason that you could not harness something like this to an accelerator or incubator program for a share in the best ideas.
Thanks for sharing the link. Building up our customer base, from the ground up, via accelerators/incubators, is something that is definitely on our minds.
