Mozilla Plugin Panel (MPP) allows you to embed any Mozilla web browser plugin into a GUI application, without using Mozilla at all.
Nice component! It's sad that it isn't updated. I tried to replace NPSWF32.dll by the current version (found in C:\Windows\System32\Macromed\Flash\). I replaced the name of the DLL in the code and compiled it with Lazarus 1.4.2. Unfortunately the program crashed.
