you can try to find out the URL of your skydrive account and use it with goodreader or iWorks.
Here is how you find out: SkyDrive Simple Viewer for WebDAV
For me, it worked once or twice. At present it doesn't.
yes, I linked my skydrive account to smestorage.com.
the service works very good, free.
It support file size to 50 Mb only, but normally the files that I use with iWork appa on iPad are smaller.
iOs app available too (need to buy it).
