52120 clone of Remote Desktop S/W

need a "Remote Desktop" software clone similar in size, performance, features & capabilities to those seen in programs like WinVNC, RemoteAnything, GoToAssist, & others, compiled to run on Windows Server OS, with multi-platform compatability between the "masters" & "slaves" (masters & slaves need to operate as WinVNC does, installing and interfacing with each other across all versions of Windows & Mac OS (including Windows CE)) please quote price for base package, with prices of each additional capability/modules for example, start with quote for a base package similar to RemoteAnything's DS package, then list the cost & time required to add each individual feature/capability, like CE & Mac OS versions, accounting/billing module, detailed tracking/stats/reports, session transfer/"handoff", etc.) payment will be made via escrow service, and bonus will be offered for early completion (provided all source code & final executables pass error testing and function as agreed)
