Excel Workbook object to SharePoint Document Library

Hi,

I've written an app that generates an excel workbook and writes it to a SharePoint document library. Right now I am saving the generated Excel doc to a temp folder and using the SharePoint Copy web service to then write it to the SharePoint document library before deleting it from the temp folder.

I'd like to write the excel workbook object directly to the SharePoint document library rather than going through the whole business of saving it to a temp folder before uploading to SharePoint and then deleting.

I cannot install the SharePoint object model on my box, so that's why I am using SharePoint web services. Is there a way to do this with web services or something other than the SharePoint object model?

Thanks!
