um well, i'm not sure my earlier idea would work. (unless westtek adds it themselves)
I did however find the following titles, but havn't had time to try them yet.
pocketpdf 1.0b -free (creator of ActiveTweak)
Jpeg2pdf - free
FluidPDFVPrint = $40 after trial
Filibe PDF Scanner = $10 (does basically the same thing as Jpeg2pdf)
there are also several SDK's availble, old and new.
