Used it in Delhi with 599plan(300kbps) for sometime. Good for roaming guys but no surety of complete coverage, hopefully they'll get good coverage in future

• Average guaranteed speed (between 0800 hrs and 2000 hrs)
  nothing guaranteed but it works at 80-90% of CIR
  
• Average uptime in 1 week
  depends on signal strength, no network downtime as such
  
• Do they provide public static IP?
  nope, didn't asked for one :)
  
• Any restrictions? (ports block, blacklisted ip network, etc)
  didn't experimented a lot but more or less very seemless
  
• Any fair usage policy?
  didn't encountered any
  
• Any area specific surprises?
  unavailability of signal at many places
  

Overall review
seems to be a costly option, HSDPA data cards of CDMA (photon or broadband+) are much better mobility connectivity options.
