I will let Nick, Karen and Dustin explain the official position, but we are planning to use paper forms this year for all tournaments.
By our reading, paper forms alone are perfectly legal for this year, for both VA-DC FLL (regional) and US First (national). There is an online process to request paper forms to meet national requirements (this is a two pager). The current version of the VA-DC regional tournament registration process (which is just last year's process, thankfully) uses only a paper consent.
US FIRST would love to have the information all in one place (and in the long run, this will help bring professionalism to team marketing, as they will be able to use the magic of social networking and direct marketing to bring more kids to robotics, rather than the current ad hoc school and parent posters), but we have elected to defer the added burden on parents to beyond this transition year by sticking with paper forms.
Please note that VA DC FLL is only asking for the consent form while US FIRST also asks for a demographic form. We are bringing both to our tournaments. Also, for new coaches, there is yet a third piece of paper which all teams must bring (at least 4 copies, we suggest more like 10) -- the Team Info Sheet. This is what helps judges keep track of the teams on competition day. All judges read this sheet. Many do not eat the candy that comes with it!
The registration is working beautifully this morning. A great case for not fixing what isn't broken :-)
