Extremely slow icloud transfers

Question

Hello,
The last couple of weeks I have had a terrible time downloading keynote (also pages and numbers) documents on my laptop from iCloud.  I use my desktop for most of my work.  Then go to the lecture hall or home and work on my laptop.  Recently the keynote presentations, numbers spreadsheets, and pages documents simply will not download from the cloud onto my laptop.  I just get the grayed out name and a little cloud icon is a down arrow.  They will not open.

I'd simply like to echo/confirm Ed D's comments. I cannot transfer files from one Leopard running Mac to another with anything greater than a 30% success rate and the speed at which the successful transfers occur is positively geriatric.
For me this is only the case when both computers are running Leopard. If one is on Tiger or XP and the other is Leopard transfer rates are normal and robust. For me it seems that this is a Leopard 2 Leopard problem.
I have been able to achieve normal transfer rates by pushing the file over to another computer as opposed to bringing a file over to the computer I'm using. To this end I've been using Screen Sharing to send from the remote computer to the computer I'm on. Not an elegant workaround but it works.
Opening a file from the remote computer is less than dicey an extremely frustrating. This problem is crippling for the MacBook Air...it almost defeats it's purpose. This isn't the case when using Front Row or iTunes, but it does effect Quicktime by itself (playing a file from a network drive generally fails).
