John,
I think the updates to the iOS allow this now.
I use Mobile Me. It includes iDisk (a pre-cessor to iCloud).
I opened iDisk with my MacBook and drug my html camera manual from the MacBook desktop into iCloud. It took a little while, but when it was visible in the iCloud on the iPad I just clicked on the file. It just "worked." The file opened in Safari; the hyperlinks work, also.
If you don't have MobileMe I believe Dropbox//https://www.dropbox.com will work also; there are Dropbox apps available in the App Store. It is free.
Good luck.
