Information feed

[madunix]

Dear ALL,

I am running several web servers (Apache/PHP/MySQL) with  alot of
statistical data, I got multiple request from different providers
they asked us to implement a mechanism through which the data can be
shared with them. at the moment we dont have a direct data feed
service.
I would like to know out of your experience how do you implenet data
feed services, am thinking now to provide the data through an FTP or
in a predefined email format.

Thanks
