/*
File: Math.uuid.js
Version: 1.3
Change History:
 v1.0 - first release
 v1.1 - less code and 2x performance boost (by minimizing calls to Math.random())
 v1.2 - Add support for generating non-standard uuids of arbitrary length
 v1.3 - Fixed IE7 bug (can't use []'s to access string chars.  Thanks, Brian R.)
 v1.4 - Changed method to be "Math.uuid". Added support for radix argument.  Use module pattern for better encapsulation.

/*
* Generate a random uuid.
*
* USAGE: Math.uuid(length, radix)
*   length - the desired number of characters
*   radix  - the number of allowable values for each character.
*
* EXAMPLES:
*   // No arguments  - returns RFC4122, version 4 ID
*   >>> Math.uuid()
*   "92329D39-6F5C-4520-ABFC-AAB64544E172"
*
*   // One argument - returns ID of the specified length
*   >>> Math.uuid(15)     // 15 character ID (default base=62)
*   "VcydxgltxrVZSTV"
*
*   // Two arguments - returns ID of the specified length, and radix. (Radix must be <= 62)
*   >>> Math.uuid(8, 2)  // 8 character ID (base=2)
*   "01001010"
*   >>> Math.uuid(8, 10) // 8 character ID (base=10)
*   "47473046"
*   >>> Math.uuid(8, 16) // 8 character ID (base=16)
*   "098F4D35"
*/
Math.uuid = (function() {
 // Private array of chars to use
 var CHARS = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.split('');

 return function (len, radix) {
   var chars = CHARS, uuid = [], rnd = Math.random;
   radix = radix || chars.length;

   if (len) {
     // Compact form
     for (var i = 0; i < len; i++) uuid[i] = chars[0 | rnd()*radix];
   } else {
     // rfc4122, version 4 form
     var r;

     // rfc4122 requires these characters
     uuid[8] = uuid[13] = uuid[18] = uuid[23] = '-';
     uuid[14] = '4';

     // Fill in random data.  At i==19 set the high bits of clock sequence as
     // per rfc4122, sec. 4.1.5
     for (var i = 0; i < 36; i++) {
 
    if (!uuid[i]) {
         
r = 0 | rnd()*16;
         uuid[i] = chars[(i == 19) ? (r & 0x3) | 0x8 : r & 0xf];
       }
     }
   }

   return uuid.join('');
 };
})();

// Deprecated - only here for backward compatability
var randomUUID = Math.uuid;


En LotusScript la parte más importante sería :
If i=20 Then
uuid(i) = chars( ( r And &H3 ) Or &H8 )
Else
uuid(i) = chars( r And &HF )
End If

Tenéis todo muy bien explicado en el artículo de Jake. Cuando tenga un rato lo traduciré y lo subiré al blog.
