I have, and sometimes it goes well, but you don't hear about those cases. OTOH, you have to remember that the IRS is already developing a fairly complex bit of software which allows the tax companies to "e-file" the tax returns. Then they are verifying those companies results in house against the data they already have. At which point, apparently the returns are either rejected, or assigned some kind of weight for a human inspector to come along and review for whether a formal audit should be undertaken. So, its quite possible that cutting out the e-file portion and replacing it with a webUI actually simplifies things.
