I think it actually is mostly a Vespa on the inside. That's a QUASAR 250ie engine in there.
The Scomadi is a production version of customs done by these guys:

It's also basically the same scoot as the CMSI L-series. That project is dead at this point, so don't count on this coming to the US. Scomadi says they're doing a 10-scoot limited run of these for the UK. Looks like rather than have all their work be in vain, they're just going to build some and sell them now that they don't have a distributor/backer to actually manufacture these.
This has been several years in development and there are no signs of it coming out anytime soon. Their 2nd prototype was shown over 2 years ago. Since then, they've gone from steel to carbon fiber body panels and have launched a web site.
If you want one, it's going to cost a buttload. If you drop it, you're SOL.
