Sharepoint 2010 javascript client object model - downloading items and item attachments?

Is there a way, so that you can download the items from a list and all its item attachment files in one context call? Currently I am downloading all the items, then looping through each item, and getting its item id, then then making X ajax calls where X is the number of items, to get the item's attachments. Because I need the item ID so I know the link of the attachment folder.

Is there a way to do all this in 1 ajax call?

Note: this is for client object model, javascript code.

Thanks
