Hi Radek,
I know this is no help at the moment, but given the occasion I though about if the Czech community is interested in running a domain like "warpstock.cz". I can offer to see if/what we (warpstock.eu) can offer for this in case there is demand. It will certainly be something Typo3-run I guess - so if you (they) can live with that and are interested, let me know.
BTW: NICE profile picture!

Cheers,
Thomas
