While it's an interesting project (I had fun playing with it) you really shouldn't be relying on remote sources of entropy for security purposes.

Generally the entropy needs to be secret to be effective so sourcing remote entropy reduces your security to that of the transport security (if any). It's hard to imagine a situation where you have a secure transport mechanism but do not have enough entropy since most encryption schemes that you might use to secure the transmission require secure random number generation.

Disclaimer: I am not a cryptographer, cryptology frightens and confuses me.
