This is only experimental but it's interesting. The team behind Google's Native Client which lets you run C, C++ and other software within Chrome have announced that Pepper 24 (the version number matches the releases of Chrome- the current version of beta Chrome is 24.0.1312.40) will have a new experiment toolchain PNaCl ( Portable Native Client) with an architecture independent exe (pexe). These are translated into architecture specific nexe files which run safely within Chrome.
NaCl has always been a work in process but its coming along great guns. Pepper 23 has a nacl version of gdb that works on Linux, Mac and Windows and 24 comes with a new library pthreads-win32 for Win 32. NaCl lets you write applications in C/C++ and other languages that runs much faster yet as safe (using a double sandbox!) as JavaScript web applications.
