Basically, I just need to know approx the percentage of people that have UPnP enabled at current times (2010) so that I can make a business desicion on a software product (built for Windows only) I'm building.
I understand this would mainly be influenced by the number of routers that have this enabled by default, if i am not mistaken, they never used to have it on by default but recently (last 2 years or so - correct me if i'm wrong) started having it enabled by default because (once again, correct me if i am wrong) it is a requirement for them (router manufactorers) to have UPnP enabled by default if they want the "Windows Vista/7 Ready/Compatible" sticker on their routers.
Feel free to correct me on any of that, just an approximate % is ok just to get a ballpark figure - even if the percentage reflects "your opinion" as opposed to actual fact, that is ok and definitely useful for me (please state if its your opinion or guess or based on a source, please try to include source if so).
In addition to this, if any of you know the progression of UPnP being enabled or disabled by default (or which manufactorers did which in the past and present) over the last several years (from any year up until the present) for instance from 2003 to now, or 2005 to now or 2001 to now... perhaps a description of how things have changed from what you know would be very helpful, perhaps also including including details of changes in why manufactorers moved from disabled/enabled by default to the other and why and where the future is leading (or moving towards) in terms of this percentage or proportion.
Thank you very much, basically, a general percentage and if possible/available general change/movement of this percentage over the last several years or decade would be absolutely useful for me and i am sure for several others.
Thanks!
PS: I'm mainly installing on SOHO routers.
