I am not very technical but...

1) do encrypted emails through Datacoin wallet
2) do a flashing video for Datacoin selling to the masses (offer it in a competition)
3) have you seen curecoin and Gridcoin and how their mining is used for research?
4) offer an encrypting tool on the datacoin wallet - so that a person can send a file to a receiver who can only open it with a datacoin wallet (wallet to wallet encryption)
