Are you sure? I mean, sure-sure?
I have no problems using the "send to device" on my wife's tab. She uses FBReader and calibre is configured to send there epubs. It simply works.
As to the Kindle reader app, you could use the send-to-kindle email addrees from calibre or using you favorite email client.
