Just had a thought: cover your ass. Send an email to the effect of “I will implement this, but I need it to be known that I’ve looked into it and other IT professionals don’t think it’s a great idea as it presents a security risk.”
I’ve been in IT since 1998. The two best tools are: a kettle so you can go make a cuppa and see if it fixes itself and a Teflon suit.
This is a great suggestion. I think that given the response on here I might first try the “Have you considered sharepoint” approach, with a few pro’s thrown in. We have a 1Gbps dedicated line for < 30 of us, so whilst it will get a workout I reckon it should cope.
As for the best IT tools, you forgot about the special turn-it-off-and-on-again finger that no end user seems to possess.
