According to the license agreement at http://www.wolfram.com/terms/MathematicaLicenseAgreement.pdf , the prohibited uses include: "All uses of the Software and other elements of the Product not specifically stated in the Permitted Uses section of this Agreement are prohibited, including without limitation:" ... "h. allowing access to the Product by any user other than Licensee, including without limitation, access to the Product via a web server which is only allowed pursuant to a valid webMathematicaTM license agreement;" (you might check to see if the text is the same in your license agreement---I believe the above is for a single-user license). I asked my campus Wolfram representative once if I could have a wiki that would allow students to run mathematica calculations (we had a site license and Mathematica was on all the student labs). After he talked with Wolfram, I was told that I would need a webMathematica something-or-other and that I wasn't allowed to provide web access using regular mathematica. Incidentally, that's about when I started discovering the Axiom wiki and started learning more about Sage :). Of course, if there is doubt, we ought to have the questions clarified by an official representative of Wolfram. -Jason --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
