David just sent me the following code to make gource work with Plastic.

Build it and create a pgource.exe and then type (all in one line)

$ cm log -f=0 --allbranches 
 --csFormat="{items}" 
 --itemformat=
   "{date}|{owner}|{shortstatus}
    |{path}{newline}" 
 | pgource.exe > p.log

Now you've a gource ready log! Just play it and enjoy

$ gource p.log

using System;
using System.Collections;
using System.Globalization;

namespace pgource
{
    class Class1
    {
        private static string mCulture = "en-us";
        private static Stack mReversedLines = new Stack();

        [STAThread]
        static void Main(string[] args)
        {
            ProcessArgs(args);
            ReadInput();
            PrintOutput();
        }

        private static void ProcessArgs(string[] args)
        {
            if (args.Length == 1) mCulture = args[0];
        }

        private static void ReadInput()
        {
            string line;

            while ( (line = Console.ReadLine()) != null)
            {
                ProcessLine(line);
            }
        }

        private static void ProcessLine(string line)
        {
            if (line == string.Empty) return;

            string[] parts = line.Split('|');

            if (parts.Length != 4) return;

            ProcessParts(parts);
        }

        private static void ProcessParts(string[] parts)
        {
            // 3/28/2010 9:10:22 PM|dave|C|c:\develop\Form1.resx

            mReversedLines.Push(string.Format("{0}|{1}|{2}|{3}", 
                GetUnixDate(parts[0]),
                parts[1],
                GetStatus(parts[2]),
                GetPath(parts[3])));
        }

        private static int GetUnixDate(string date)
        {
            CultureInfo c = new CultureInfo(mCulture);

            DateTime parsedDate = DateTime.Parse(date, c, DateTimeStyles.None);

            return (int)((parsedDate - new DateTime(1970, 1, 1)).TotalSeconds);
        }

        private static string GetStatus(string status)
        {
            switch (status)
            {
                case "A": return "A";
                case "R": return "D";
                default: return "M";
            }
        }

        private static string GetPath(string path)
        {
            return path.Replace('\\', '/').Replace(':', '_');
        }

        private static void PrintOutput()
        {
            while (mReversedLines.Count > 0)
            {
                Console.WriteLine(mReversedLines.Pop() as string);
            }
        }
    }
}
