where to put a public worksheet referenced in a paper?

edit

I'll be publishing a paper that depends on calculations in a Sage worksheet. What is the standard practice for publishing such a worksheet? I'll attach in to the arXiv submission a printout of the worksheet and a .sobj file containing the worksheet. I'd also like to make the worksheet available to readers who do not have Sage installations of their own. I could say: 'get an account at sagenb.org and upload the worksheet', but that seems a bit awkward. I can't simply publish the worksheet from our local Sage installation because I need (in other worksheets) our Sage installation to allow running shell scripts from a Sage worksheet, which would be a bad security hole in a published worksheet.
