I like the above drafts, and both have good potential with tweaks to the non-graphic letters; something more distinctive but complimentary.

Btw, I still prefer Netcodes (in spite of your argument against) to Netcash, but would actually choose Vibes (and VibeTube, which IMO runs off the tongue easier and has more of a ring to it than vibes.tube, which creates sibilance when I say it). I can see the appeal of not having to cover all the portmanteau permutations with Vibes.

And how about vibetube.click which seems to be available at http://goo.gl/RuvTzB scrolling right down.

An honourable mention to Mobimo too.
