wolfram-cdf

For my Skeptics working group I wrote a program in Mathematica to test a dowser's ability to assess the status of persons shown to them by means of photographs. For a null measurement I distributed this document to my group's members in CDF form (the new v8 Computable Document Format, meant to be run with the CDF-player ). On my computer (using mma) it all works fine, but the others can't export the data (the program does an export to an Excel file). On reading the fine print I see that the player doesn't support Export. So my question is: Is there any way to get data out of CDF-player? For

Simple question, but I am asking just to make sure I am not overlooking an obvious solution which can be much more efficient. If one has large data buffer, say very large list, that needs to be updated, and wanted to pass it to a function to do the updating inside the function as in a = Table[0,{10}] a = update[a] and since I can't use pass by reference (in a CDF, one can't change the Atrributes of a function to anything, such as HoldFirst), then I am forced to make a copy of the list inside the function itself in order to update it, and return back the copy. My question, other than using
